40 LABORATORY OUTLINE OF NEUROLOGY 



33. In the interest of economy, both of material and of the 

 student's time, it is desirable that in the first dissection the 

 order of procedure here outlined be followed exactly. In par- 

 ticular, in the dissection of the sheep (or of the human brain in 

 case this is used for the first dissection) where some of the 

 dissections are to be made on the right side of the brain and some 

 on the left, the dissection must be made on the side directed in 

 order not to interfere with later procedures. The appropriate 

 portion of the Laboratory Outline should be read and text- 

 books consulted before each laboratory exercise, and a certain 

 general familiarity with the parts to be studied thus secured in 

 advance. 



Both laboratory and lecture work should be daily supple- 

 mented by careful study of the text-books and atlases. But the 

 laboratory notebook is primarily a record of your own observa- 

 tions. The notebook should always show the source of any 

 second-hand matter introduced from text-books and other 

 authorities by way of correlation. Record the observations so 

 far as possible by drawings. Make them neat. See that they 

 are fully and neatly labeled. When for any reason the drawings 

 specified do not record fully or faithfully your observations, sup- 

 plement them by written notes. These must be written in ink 

 and should be interleaved with the drawings. Each page of 

 drawings should have an appropriate heading. Do not crowd 

 your drawings; avoid especially the promiscuous mixing of un- 

 related notes on the same page. Excellent directions for labor- 

 atory drawing will be found in the first thirty pages of Hardesty's 

 Laboratory Guide for Histology ('08) and in Guyer's Animal 

 Micrology ('17), pp. 159-172. 



34. Terminology. — The confusion in the use of terms has been 

 more serious in neurology than in most other departments of 

 anatomy The only widely used standard is the official list of 

 the German Anatomical Society, commonly referred to as the 

 B NA (see Barker's Anatomical Terminology and Eycleshymer's 

 Anatomical Names), and it is necessary to be familiar with 

 these terms; they should be used in your laboratory notes. 

 Some of our anatomists, however, do not use these terms con- 

 sistently. Accordingly, the student must be familiar with some 

 other of the more commonly used names also. The B NA terms
